Quintessence square Recessed luminaires with LED

ERCO Quintessence square Recessed luminaires Introduction

Consistent system design is a characteristic feature of the Quintessence square recessedluminaires. Perfect combination of the lamp, lens and control gear results in maximum efficiency. The high-quality lighting technology and the glare protection with darklight technology are based on the principles of efficient visual comfort. The modular structure allows many different variations to be made with identical mounting detail and luminaire edge. Simple mounting makes for a highly economical installation. All Quintessence recessed luminaires use the same design principle for mounting frames, meaning that the different lamp types and characteristics are not only easy to combine, but also to interchange.

Reflection

Especially in LEDs where high visual comfort is required ERCO uses optical systems based on the principle of reflection. This is the case in the Quintessence range of recessed luminaires with darklight reflectors. Here, to provide optimum glare control, the illuminated plane of the diffuser is set back from the plane of the mounting surface. This allows the exact cut-off angle to be defined. Darklight reflectors with Spherolit wallwasher segments produce asymmetrical light intensity distributions for energy efficient washlights and double washlights. To meet the stringent quality requirements, ERCO carries out all calculation, design and production work in-house.

Light mixer The upper reflector of Quintessence LED downlights is divided into eight segments and is made of mirror-finish aluminium. The reflections within this light mixer ensure the best possible colour mixing from immediately in front of the luminaire especially with RGBW LED modules.

Diffuser The purpose of the diffuser technology is to optimise the visual comfort. The frosted glass diffuser reduces the high luminance of the individual LEDs and disperses this evenly across its surface to reduce the glare. The diffuser technology enables the design and construction of high-quality, energy-efficient washlights.

Spherolit wallwasher To achieve the uniform vertical illuminances required for wallwashing, one segment of the Darklight reflector is provided with spherolites. In the photo, the diffuser has been removed to show the position of the LED module. The patented reflector technology results in the light on the wall beginning just below the ceiling.
